Detailed description of the invention
Embodiments of the invention are described below in detail, and the example of described embodiment is shown in the drawings, wherein certainly
Begin to same or similar label eventually represent same or similar element or there is the unit of same or like function
Part.The embodiment described below with reference to accompanying drawing is exemplary, it is intended to be used for explaining the present invention, and not
It is understood that as limitation of the present invention.
As shown in Figure 1, Figure 2 and Figure 3, a kind of trimaran according to embodiments of the present invention, including main hull
100, the first lamellar body the 200, second lamellar body 300 and deck 400.
First lamellar body 200 and the second lamellar body 300 are symmetrically distributed in the both sides of main hull 100, the first lamellar body 200
Being positioned on the left of main hull 100, the second lamellar body 300 is positioned on the right side of main hull 100, is fixed by deck 400
Together.Deck 400 is positioned at main hull the 100, first lamellar body 200 and the top of the second lamellar body 300.
Below main hull 100, front side is provided with front hydrofoil 110, and front hydrofoil 110 is by front hydrofoil strut 120
Fixing with main hull 100 and be connected, the plane of flattening of front hydrofoil 110 and main hull 100 preset the angle of attack in first.
As shown in Figure 4, front hydrofoil strut 120 and the fixing connection of front hydrofoil, orthogonal.Below main hull 100
Rear side is provided with faulted-stage structure 150, and faulted-stage structure 150 is along the most stepped rising in hull direction.
Hydrofoil 210 after being provided with first below first lamellar body 200, hydrofoil 210 and main hull 100 after first
Fixing connection, and after first, the plane of flattening of hydrofoil 210 and main hull 100 preset the angle of attack in second.Such as Fig. 5
Shown in, it being embedded with the first wing flap 220 after first on hydrofoil 210, the first wing flap 220 is by the first connecting shaft
After 230 and first, hydrofoil 210 is rotationally connected in perpendicular, and the first connecting shaft 230 and hull direction
Vertically (as illustrated in fig. 1 and 2, hull direction is fore-and-aft direction as depicted).
Hydrofoil 310 after being provided with second below second lamellar body 300, hydrofoil 310 and main hull 100 after second
Fixing connection, and after second, the plane of flattening of hydrofoil 310 and main hull 100 preset the angle of attack in the 3rd.After second
Being embedded with the second wing flap 320 on hydrofoil 310, the second wing flap 320 is by after the second connecting shaft 330 and second
Hydrofoil 310 is rotationally connected in perpendicular, and the second connecting shaft 330 is vertical with hull direction (such as Fig. 1
Shown in 2, hull direction is fore-and-aft direction as depicted).
As further improvement of this embodiment, after first after hydrofoil 210 and second hydrofoil 310 about main ship
Body 100 is symmetrical, and the first wing flap 220 and the second wing flap 320 are also symmetrical about main hull 100.
When the trimaran wing navigates, by fluid hydrofoil 310 after hydrofoil 210 and second after front hydrofoil 110, first
The pressure differential of upper and lower surface provides certain lift, and then improves speed.
As further improvement of this embodiment, after first, after hydrofoil 210 and second, hydrofoil 310 passes through first
After rear hydrofoil strut and second, hydrofoil strut is fixing with main hull 100 is connected.Hydrofoil strut and second after first
Rear hydrofoil strut lays respectively at main hull the 100, first lamellar body 200 and the bottom of the second lamellar body 300 and symmetry
Distribution, plays the effect supporting hydrofoil.
As further improvement of this embodiment, the first wing flap 220 and the second wing flap 320 are respectively arranged in two
The centre position of individual rear hydrofoil.First wing flap 220 and the second wing flap 320 are respectively by drive mechanism and motor
It is connected.When trimaran navigates by water, realize ship by controlling the suitable angle of attack changing wing flap of motor
The operation attitude of oceangoing ship carries out assist control.Wherein, motor can be single flow motor or AC system motor.
As further improvement of this embodiment, main hull 100 afterbody is provided with faulted-stage structure 150, permissible
Reduce resistance during high speed operation, improve speed, reduce energy consumption.
As further improvement of this embodiment, hydrofoil after hydrofoil 210 and second after front hydrofoil 110, first
The outer surface of 310 is arcwall face, specifically, and hydrofoil after hydrofoil 210 and second after front hydrofoil 110, first

As further improvement of this embodiment, hydrofoil after hydrofoil 210, second after front hydrofoil 110, first
310, the first wing flap 220 and the second wing flap 320 use NACA series aerofoil sections, and front hydrofoil 110, first
After rear hydrofoil 210, second, hydrofoil the 310, first wing flap 220 keeps aerofoil profile consistent with the second wing flap 320, can
To reduce the resistance that hull is subject to.
As further improvement of this embodiment, front hydrofoil, after first after hydrofoil and second span of hydrofoil with
The length ratio of wing chord is 0.2～0.25, it is ensured that hull is by less resistance.
As shown in Figure 6, wherein, x-axis direction is surge motion direction, is rolling motion direction around x-axis, y
Direction of principal axis is swaying motion direction, is pitching around y-axis, and z-axis direction is heave movement, around z-axis is
Yawing campaign.
Explanation as a example by controlling the heave movement of trimaran, pitching, rolling motion and course/heeling motion
The specific implementation of the present invention.
When the trimaran wing navigates, its speed, the faulted-stage structure of afterbody can produce one under action of a fluid
Fixed air film, slightly lifts ship, thus reduces wet water area, reduces resistance.
When trimaran body navigates, current produce pressure differential in the upper and lower surface of three hydrofoils, thus are trimaran
Certain lift is provided.When trimaran is transformed into foil-borne by body boat, the suitable angle of attack increasing wing flap,
Thus provide boats and ships to take off required lift.
When trimaran produces rolling motion around hull coordinate system x-axis, adjustment the first wing flap 220 that can be suitable
With the angle of attack differential change of the second wing flap 320, thus produce righting moment.If producing heel to the left, then increase
The angle of attack of big first wing flap 220, reduces the angle of attack of the second wing flap 320, produces righting moment；If produce to
Right heel, then reduce the angle of attack of the first wing flap 220, increases the angle of attack of the second wing flap 320, produces restoring force
Square, thus assist and reduce certain rolling.
When trimaran produces trim by stem pitching around hull coordinate system y-axis, reduction trimaran that can be suitable
First wing flap 220 and the angle of attack of the second wing flap 320, reduce lift, thus assist reduction pitching；
If producing the pitching that tail inclines, then increase first wing flap 220 and the angle of attack of the second wing flap 320, it is provided that one
Determine lift, reduce pitching.
When the trimaran wing navigates around z-axis in time carrying out divertical motion, hull may be caused to produce heel, if to
When left steering produces left heel, first wing flap 220 angle of attack of hydrofoil 210 after first can be adjusted and increase and the
After two, the angle of attack of the second wing flap 320 of hydrofoil 310 reduces, so that trimaran produces righting moment, reduces
The heel of hull.
A kind of trimaran according to embodiments of the present invention has the advantage that
(1) there is certain pitching stabilization effect.When hull bigger pitch angle occurs due to factors such as waves, pass through
Two wing flaps being positioned at afterbody can suitably reduce pitching.
(2) reduction rolling can be assisted.Can be assisted by two wing flaps and reduce certain rolling motion.
(3) ship resistance is reduced during high speed.Owing to afterbody is designed as faulted-stage structure, when trimaran high speed operation,
Certain resistance can be reduced, improve speed.
